What drink will invigorate the best?
Coffee
He will make you live forever. And he can kill you. The caffeine content in this drink is to 1,500 milligrams per liter. However, systematic consumption at 1,000 milligrams per day of caffeine, theobromine and theophylline cause a person permanent need in them, resembling alcohol addiction.
However, in case of moderate coffee consumption improves short-term attention and ability to concentrate, especially when the person is tired. At the same time increases productivity, improves memory and even mood.
And yet this wonderful drink significantly reduces the risk of developing liver cirrhosis and even breast cancer.
By the way, a recent study by American scientists showed that when switching from regular coffee to decaf productivity in one of the local companies fell by 19%.

Part of energy drinks taurine causes a lot of doubt among physicians, but scientists say that in the quantities in which it is contained in drinks, taurine is safe for health.

In General, this is not an option.
Sweet drinks
Cola and similar drinks do not have a tonic action and contain a lethal dose of sugar. Do not recommend.
Cocoa
